LYMAN R. BLAKE, oii Bos'roN, MASSACHUSETTS IMPROVED NAILEDI'BOQT OR SHOE.

Specification forming part of Letters Patent No. 49,219, dated August 8, 1865. I

To all whom it may concern Be it known that I, LYMAN R. BLAKE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Shoe; and 1 do hereby declare that the following, taken in connection with the drawing which accompanies and forms partof this specification, is a description of my invention sufficient to enable those skilled in the art to pracvention that the nails have an inclination given to them in the direction of the line of nails.

The drawing represents a section of the sole, vamp, and insoleot a shoe taken in the plane of the line of nails.

a denotes the outer sole; b, the vamp; c, the inner sole, and d the nails. Some of .the nails are represented as driven entirely in and clinched upon the inner surface ofthe insole,

whileothers are shown as only partially driven; The solewt is shown on one end of the drawing as channeled, the flap being turned over and pressed down upon the heads of the nails when the shoe is finishethas seen at e, to give a smoothed outer finish to the sole, while at the other end the heads of the nails are embedded directly in the outer surface of the sole, the heads appearing therein in the finished shoe.

1n the employment of nails in shoe con struction as heretofore practised for uniting soles to their uppers, they are driven in straight or perpendicularly to the plane of that surface of the boot or shoe in which they enter, the

adjacent nails being practically parallel, and' only deviating, it'at all, from this parallelism through accident. Owing to the non-elasticity and rigidity of the nails, however, when any enlargementof the holes inwhich the nails are driven takes place by wear or otherwise,

the nails do not enlarge a head-up to fill such enlargement as with woodenpegs, and the seam or joint between the sole and vamp opens, the more especially after the heads of the nails are worn away. To remedy this defect I drive the alternate nails at an inclinationwith Te spect to each other,when,aswill be readily un derstood, the sole a cannot draw away from the vamp without tearing the sole or bringing the nails -with it-rosults which cannot. follow from wear. v j

Where the stock is thick and heavy the nails maybe driven quite closely together, or may cross, as seen at f, a lateral inclination being given to the nails in driving to prevent -1I1 ]l1 rious contact. With nails driven perpendicularly to the face of the sole; the tread 'ot' the foot being square upon the end of the nails and in the direction lengthwise ofsuch nails, there is no give or yield to the nails, and a shoe so made is hard or painful to wear; but with the inclined application of the nails pressure is so'brought upon them that they yield to the tread and give a degree of elasticity to the sole. as will be readily understood, and the square tread upon the inclined nails 'does not push t them up end-wise against the foot, but has a tendency to bend them awaytherefrom.

I claim A shoe in which the vamp and sole are united by nails having an inclination with respectto each other, substantially as set forth.

LYMAN R. BLAKE.
